Researchers have developed a new framework called Moira for hierarchical reinforcement learning, specifically designed for complex sequential decision-making problems like pair trading. This approach utilizes large language models (LLMs) for both high-level abstraction and low-level execution, optimizing policies through prompt updates rather than traditional gradient-based fine-tuning. The system leverages textual feedback to adapt and improve performance, showing significant gains over existing methods on real-world market data. AI
